Ball mills are typically used in the ceramic, glass, paint, pyrotechnics and porcelain industries and are also often used in food and chocolate production. By choosing the right combination of rotational speed, ball material, size and weight it is possible to process a wide range of materials
Product Advantages. Faster and finer grinding than any other ball mill. Speed of 2000 min-1 allow for ultra-fast pulverization of the sample. Water cooling permits continuous operation without cool down breaks. Temperature-controlled grinding. Narrow particle size distribution thanks to special jar design which improves mixing of the sample.
The ball mill works on the following principle size reduction is achieved by impact from metal balls in a rotating drum. The drum is loaded with grinding material and balls. When rotating, the material is crushed as a result of abrasive effect, chipping action and impact force.
How does ball mill work The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground.
